Hi, thx for the response even in case of such a old post.

I actually made a mistake when I wrote the question because I was copying characters of teahong.com and missed the fact that the other character your site uses has a ‘mu’ component in the 欉. I intended to write 丛 (叢). 欉 is actually a variant I see for a first time.

So my point I was trying to make is that I encounter 单丛 on regular basis.
Later I found that even Wikipedia entry on Dancongs in Chinese, addresses this issue of different character usage:
https://zh.wikipedia.org/wiki/%E5%87%A4%E5%87%B0%E5%8D%95%E4%B8%9B

My Chinese is so entry level I can’t really satisfyingly translate it. But they quote this article as a source:

But I assume you don’t agree with their position. As for me, I don’t have a horse in this. I am just glad, I got a chance to learn some more, thanks to your articles and willingness to answer my questions. 🙂

Also, I would love the see the book Mr. Huang wrote. Thank you for that as well.
